Nice game, really liked the 4 directions attack, i swear i finished hard with 1 hp O.o. Only thing that i didn't like much was the delayed sound, dunno if it's only a problem on my side tho.
Was kinda too easy, repetitive most power-ups are useless 3/5. And this is only related to spore if you consider the celular phase, and that type of game "bigger eats smaller" as been around for ages.
